Title: Improvements in and relating to optically readable discs and disc recording apparatus
Inventor: FAESSEN LOUIS MARIE HUBERTUS
IPC: G11B7/004
Filed: 1997-07-14
Abstract: An optical disc and an optical disc recording apparatus have been disclosed which provide an improved protection against undesired or illegal copying. Information on optical discs is arranged in sectors, which each has an address label. The address value of the address labels increases linearly from the start of the disc or from the start of the program area of the disc. The address labels of specific sectors, which may have an informationless content, are given different, e.g. zero, address values, which prevent copying CD-ROM discs on a standard CD-Recorder apparatus. Said address labels may be stored in the main data stream or e.g. the subcode channel of a CD system.

Patent CA-2242989-A1 (CA)
Inventor: HENDERSON DANNY L
IPC: C03B37/027
Filed: 1997-01-21
Abstract: Disclosed are methods for reducing polarization mode dispersion (PMD) in single mode fiber by spinning the fiber during the drawing process in accordance with a spin function having sufficient harmonic content to achieve low levels of PMD for commercial fibers for which the beat lengths of the fibers, including the beat lengths of different portions of the fibers, are available and thus not readily known in advance. The spin functions disclosed take advantage of certain resonances in energy transfer between polarization modes to achieve substantial reductions in PMD for a wide range of beat lengths. Examples of suitable spin functions include frequency-modulated and amplitude-modulated sine waves.

Title: Procedure and apparatus for the deceleration of an elevator
Inventor: SAARIKOSKI TAPIO
IPC: B66B1/30
Filed: 1997-04-30
Abstract: To decelerate an elevator to a floor, the position of the elevator is determined and this data is used to calculate a required deceleration value ad; (62) with which the speed and deceleration of the elevator are reduced to zero upon reaching the floor and the deceleration changes by the amount of a constant jerk during the final round-off. A deceleration reference value ade is repeatedly compared with the required deceleration value (64) determined on the basis of the position data and deceleration reference value is changed towards the required deceleration value (65, 66) based on the position data. During deceleration, the system is monitored to establish the point of time when the conditions for starting the final round-off are valid (72) and the final round-off (74) is started accordingly. After the starting point of the final round-off, a speed reference v ref is determined using a jerk J4 that fulfills the starting conditions.

Inventor: CSOMO JEAN-FRANCOIS
IPC: H04B1/7075
Filed: 1998-11-23
Abstract: The disclosure relates to digital transmission systems in which information in binary form is transmitted in pseudo-random sequences so as to enable the measurement, at reception, of the quality of the transmission. The synchronization at reception is obtained by loading the shift register of the pseudo-random generator with the code contained in a shift register that receives the binary signals transmitted. This loading is done whenever an error counter reaches a value EMAX. The error counter is reset at zero whenever the number of binary signals received reaches a value LMAX. The disclosed device and method can be applied to systems for the transmission of digital television signals.

Title: Measuring distance
Inventor: WOOLLEY LOUIS A
IPC: G06Q10/08
Filed: 1997-06-26
Abstract: An object in a storage area or moving vehicle is monitored by attaching an electronic tag (16) to the object (12). An electronic device (15) detects the presence of the object by communicating with the tag while the object is in storage or is being moved by the vehicle. The tags may also determine the location of an attached object and may reroute the object if it deviates from a given shipping schedule.  A group of objects is monitored by two electronic tags, each attached to an object in the group. Each tag has circuitry for communicating information relating to an object in the group to a second tag.  Each tag also includes a memory connected to the circuitry that is capable of storing the information, and a controller connected to the memory and the circuitry. A distance is measured by transmitting multiple symbols from one object to another object, having the symbols returned such that the symbols measured round-trip times are not all identical, and calculating the distance using the measured round-trip times.

Filed: 1997-09-24
Abstract: A small liquid sample (24) to be tested is contained within an annulus (18) on the upper surface (14) of a substrate (12). In one embodiment, a reagent diffuses into the sample through a membrane (28) in a junction hole (26). the junction hole connecting upper (14) and lower (16) surfaces of the substrates. Optical measuring equipment (70, 72) detects a measurable change in an optical property of the sample.  In an alternate embodiment, a flow of gas (30) directed at a small liquid sample (24), causes the sample to flow in a controlled manner over the surface of an electrode (20), disposed on the substrate surface (14). In another alternate enbodiment, a spacial averaging electrode (20) is disposed in a non-homogeneous sample (24). Highly reproducible and accurate hydrodynamic electrochemical studies and analyses of microliter size samples are thus achievable, without the need for moving mechanical parts.

Abstract: A cutting nozzle for a postmixed oxy-fuel gas torch is described. The cutting nozzle is an integral body having a cylindrical shroud which surrounds and extends away from gas discharge orifices in a gas discharge end of the nozzle. The cutting nozzle has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of preheat oxygen and fuel gas. The advantages include reduced machining time and material waste. The coupling of the nozzle to the torch is also facilitated and high quality performance of the cutting nozzle is promoted because alignment of the cutting nozzle in the torch head is ensured.
